I've used them before ( not for beer though) they will burn up rather quickly if you let them run dry at all...or even if you don't run them dry. I've bought and thrown away about six of those suckers.

In my experience they aren't built to last very long hence the low price, I will say they will do the trick...slowly, then eventually fail

None of them say anything about being food-grade. They appear to all be made for moving non-potable water. For $7-15 there is no way they're going to be much better than a steel shaft coupled by a greasy bearing, which is not something I want my wort going through, regardless of what temperature the pump can handle.

Good point, I hadn't considered what a greased bearing and what it would do to mash water.
